Happy Pi Day

Have you ever wondered what’s inside a computer keyboard?

Well, my little engineers don’t need to wonder anymore – they know! 🙂

We celebrated Pi Day yesterday by opening two old computer keyboards and popping all of the little keys outside. It kept 5 kids busy for over an hour so I think it was a big hit! They took turns with the grown-up tools and  patiently unscrewed every last screw that was holding the parts together.

Now we have a box filled with computer scraps – I’m thinking robots… let’s see what the kids come up with! They often take me on a totally different journey. For example, I would never think of using the keyboard parts to create a shaker 😉

 

Pink glasses for everyone!

What color glasses would you wear if you had a choice?

We explored light, colors and color mixing with these awesome glasses. Kids had a blast and tried one, two and even six of them at the same time.

‘It is orange!’ cried one.

‘I made it really dark! It’s so dark I don’t even see anything’ laughed the other one.

‘I have two colored eyes! One yellow and one blue!’

Then they tried mixing the colors on the overhead projector and even on the light table… sharing the goggles with each other and talking about the way the colors made them feel. It was really fun and it made me think they are SO ready for art lessons about secondary colors. YAY!

Borax Snowflakes

Would you like to make some amazing crystals?

It’s much easier than you may think. Here is how to make the snowflake:

First cut a pipe cleaner into three pieces and combined them in the middle. Then mix hot water and borax (1 cup of water and 3 tablespoons of borax) and tie the snowflake to a pencil with a thin yarn or thread.

Dip the snowflake in the borax solution and leave it in overnight (or for at least four hours). Try not to move the cup in that time. Make sure the snowflake does not rest on the bottom of the cup. It could get stuck to it and that’s no fun.

You can add food coloring to tint your creation as well.

Btw, what is BORAX?

Chemically, it is called sodium borate but you may have it in your laundry room. If not, it can be easily purchased for a couple of dollars in the laundry section of almost any grocery (or drug) store. It is a soft, white powder that easily dissolves in water and has many uses. It can remove many stains and deodorize a garbage can. It can put out a small fire and kill cockroaches (that’s why you should not eat it either). It can remove rust, treat athlete’s foot and wash your laundry. And on top of that it can grow amazing crystals in only couple of hours 🙂
